The Role of Psychological Distress in the Relationship between the Severity of Pressure Injury and Pain Intensity in Hospitalized Adults.

AIMS: To examine the effect of psychological distress in mediating the relationship between the severity of pressure injury and pain intensity in hospitalized adults.

BACKGROUND: Despite the prevalence of pressure injury (previously known as pressure ulcers) in hospitalized adults, the current knowledge of pain associated with pressure injury is limited and findings are inconsistent. There is also a lack of understanding of the relationship between psychological distress and pain from pressure injury.

DESIGN: Retrospective cross-sectional secondary analysis of data from electronic health records.

METHODS: The data were retrieved from the third day of admission in the period between 2013 - 2016 through the Integrated Data Repository. Electronic health records were reviewed to collect data as needed. The mediation effect was tested by using path analysis implemented through Mplus.

RESULTS: Path analysis revealed that the severity of pressure injuries and psychological distress have significant direct effects on pain intensity in hospitalized adults. However, the relationship between the severity of pressure injury and pain intensity was not significantly mediated by psychological distress.

CONCLUSIONS: Hospitalized adults who have more severe pressure injury and more treatments for psychological distress experienced greater pain intensity. Healthcare providers must pay attention to treating psychological distress among hospitalized adults to manage pain. Further study is needed to validate these findings and it should incorporate more appropriate measures of psychological distress. The lack of standardized nursing documentation in electronic health records severely limits the usefulness of data from electronic health records for nursing research.
